Different systems vary, but one of the standard ways of setting the system
time zone is to copy the appropriate time zone file from /usr/share/zoneinfo
(which is a standard location for time zones to be stored - nothing to do with
KDE) into /etc/localtime. If KDE is actually setting the _system_ time zone as
opposed to the individual user's time zone, this copying to /etc/localtime is to
be expected - it will be done by the standard process which KDE uses to set
the system time zone. If you have previously customised /etc/localtime, your
customisation will therefore be overwritten when KDE sets the system time
zone.
